I've always wondered how pro bodybuilders, dudes who bulk on like 3 grams of test a week keep their rbc from going into astronomical ranges. I mean..I have to donate a pint of blood every 2 months (always right when I'm eligible) on my 200mg/week TRT protocol JUST to remain below the dangerous zone of 55+ hematocrit. what the hell are these guys doing to control this while they're running insane dosages of test?
